Abstract
A synthetic resin guide for a transmission device comprises an elongated rail for longitudinal sliding engagement with a power transmission medium, and a rail supporting member molded as a unit with the rail. The supporting member comprises a plurality of reinforcing ribs which support the rail. The ribs are distributed along the length of the transmission device from a location adjacent one end of the rail to a location adjacent the opposite end of the rail. The guide is formed by injection molding and the reinforcing ribs extend in directions following the flow of synthetic resin during injection molding. Preferably the synthetic resin is a glass fiber reinforced resin. By forming the reinforcing ribs in this manner, high strength and toughness are imparted to the guide, and warpage and torsion, which would otherwise be encountered in a high temperature transmission environment, are reduced.
